Abstract
Official abstract text for this publication.
A process for producing high resilience flexible polyurethane foams. The process includes forming a mixture of (a) isocyanate prepolymer, (b) polymeric compounds having isocyanate-reactive groups, (c) castor oil, (d) optionally chain-extending and/or crosslinking agents, (e) catalysts, (f) blowing agents, and optionally (g) additives, and reacting the mixture to form the flexible polyurethane foam. More than 5 wt % of (c) is used, based on the total weight of components (b) to (g), and (a) is obtained by mixing diphenylmethane diisocyanate (a1) and polyol 1 (a2) and also optionally further polyols, chain extenders and/or crosslinkers, where (a2) includes a polyalkylene oxide polyol having a hydroxyl number of 30 to 60, an average functionality of 2.3 to 3.2 and a propylene oxide fraction, based on the alkylene oxide content, of 70 to 100 wt %. A polyurethane foam obtained by the process, and the use of such a foam as an auto seat.
